I think you might need to extend MPRIS to allow making image data
available instead of a URL.

This could also help with avoiding, say, gnome-shell having to make
https calls to fetch a remote cover, or third-party playback control
apps having to cross apps boundaries to get to another sandbox app's
cover art.

Maybe this new feature is what we want?

I looked through the MPRIS repo after writing the above.

Cheers
